## What is Perfect Sleep Noise?

Perfect Sleep Noise plays white, pink or brown noise, or womb sound, to help your child sleep better. The app will provide you with a personalized noise level recommendation based on the type of noise, your child’s age, and distance from the device.

This app was developed by Dr. Eric Zhou, a sleep expert with over 15 years of clinical experience helping children sleep better. The recommended levels come from research on hearing, noise standards for hospital nurseries, and studies of baby, child, and adult sleep.

Start creating the perfect sleep environment for your child with one tap, or by asking Siri. Save your favorite settings, repeat your last session, and choose how long the noise plays, or let it play continuously. While the noise plays, the screen fades to black, and the lock screen shows the time left.

The app will also allow you to track your child’s sleep quality over time. This can help provide you with important information on what the optimal noise setting is for their sleep environment. After each session, you can rate how your child slept, review it in Noise history, and create a PDF or JPG report of patterns over time that you can then share with your child’s medical team.

This app was designed with your privacy in mind. Your information is stored on your device only. None of your information is shared anywhere by the app. It is free to use, with no ads, no in-app purchases and no account.

Please remember that the recommended sound levels are estimates, which can vary based on a number of factors in your child’s sleep environment. The app does not measure sound directly, as it estimates the sound level at your child’s head based on the distance from your device, assuming your volume is set at the highest level. Remember that this app does not replace advice from your child’s doctor on what is best or safest for them.
